ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all BAE 

Systems (Operations) Limited Model 

4101 airplanes. This AD was prompted 

by a report of the failure, due to 

overheat, of a bracket on which the 

earth post (EP) for the generator and 

propeller de-ice systems is located. This 

AD requires an inspection of the 

affected EPs and attachment structure 

for damage, an inspection of the earth 

cables of the generator and propeller deice system for signs of overheating and 

arcing damage, a torque check of the 

affected EP stiff nuts, an electrical high 

current bonding check of the bracket, 

and corrective actions if necessary. We 

are issuing this AD to detect and correct 

an overheat failure of the EPs for the 

generator and propeller de-ice system, 

and possible degradation of the wing 

front spar cap and/or web, which could 

affect the structural integrity of the 

wing. 

DATES: This AD becomes effective May 

4, 2015. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all BAE Systems (Operations) 

Limited Model 4101 airplanes. The 

NPRM published in the Federal 

Register on September 3, 2014 (79 FR 

52270). The NPRM was prompted by a 

report of the failure, due to overheat, of 

a bracket on which the EP for the 

generator and propeller de-ice systems 

is located. The NPRM proposed to 

require an inspection of the affected EPs 

and attachment structure for damage, an 

inspection of the earth cables of the 

generator and propeller de-ice system 

for signs of overheating and arcing 

damage, a torque check of the affected 

EP stiff nuts, an electrical high current 

bonding check of the bracket, and 

corrective actions if necessary. We are 

issuing this AD to detect and correct an 

overheat failure of the EPs for the 

generator and propeller de-ice system, 

and possible degradation of the wing 

front spar cap and/or web, which could 

affect the structural integrity of the 

wing. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Airworthiness 

Directive 2014–0006, dated January 7, 

2014 (referred to after this as the 

Mandatory Continuing Airworthiness 

Information, or ‘‘the MCAI’’), to correct 

an unsafe condition. The MCAI states: 

An occurrence was reported involving a 

Jetstream 4100 aeroplane, where a bracket, on 

which the earth post for the generator and 

propeller de-ice systems is located, failed due 

to overheat. Although the earth post and 

cables were not damaged, the mounting 

bracket and underlying structure were 

damaged to the extent that repair of the wing 

front spar web was necessary. Furthermore, 

the aft engine cross support rod, which is 

attached to the same bracket, was found 

damaged, as a result of excessive current 


asabaliauskas on DSK5VPTVN1PROD with RULES
16556 Federal Register / Vol. 80, No. 60 / Monday, March 30, 2015 / Rules and Regulations 

load, and required replacement. The 

subsequent investigation determined that, 

due to the damage tolerance of the aft engine 

cross rod support, the rod does not present 

an airworthiness issue. However, as a 

consequence of overheat failure of the earth 

post, degradation of the wing front spar cap 

and/or web could affect the structural 

integrity of the wing. 

This condition, if not detected and 

corrected, could reduce the capacity of the 

wing to support loads, possibly resulting in 

wing structure failure and consequent loss of 

the aeroplane. 

To address this potential unsafe condition, 

BAE Systems (Operations) Ltd issued 

[Inspection] Service Bulletin (SB) J41–24–043 

[Revision 2, dated August 21, 2013] to 

provide inspection instructions. 

For the reasons described above, this 

[EASA] AD requires a one-time visual 

inspection of the affected earth posts, an 

electrical high current bonding check of the 

bracket and, if discrepancies are detected, 

accomplishment of applicable corrective 

action(s). 

The required actions include a general 

visual inspection of the affected EPs and 

attachment structure for damage; a 

general visual inspection of the earth 

cables of the generator and propeller deice system for arcing damage and signs 

of overheating of the cable insulation 

and terminal tags; a torque check of the 

EP2 and EP4 stiff nuts; an electrical high 

current bonding check of the bracket; 

and corrective actions if necessary. 

Corrective actions include repair of 

damaged structure, replacement of 

damaged cables, cleaning of all 

applicable surfaces to achieve the 

necessary resistance value, and 

correction of the torque load of EP stiff 

nuts. 

You may examine the MCAI in the 

AD docket on the Internet at http:// 

www.regulations.gov/#!documentDetail;

D=FAA-2014-0619-0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (79 

FR 52270, September 3, 2014) or on the 

determination of the cost to the public. 

Changes Made to This AD 

BAE Systems (Operations) Limited 

has issued Inspection Service Bulletin 

J41–24–043, Revision 3, dated June 16, 

2014. This service bulletin states that 

‘‘this revision does not require rework of 

the modification(s) embodied by earlier 

revision of this service bulletin.’’ We 

have revised paragraphs (g) through (k) 

of this AD to reference this service 

information. We have revised paragraph 

(l) of this AD to give credit for actions 

done prior to the effective date of this 

AD using BAE Systems (Operations) 

Limited Inspection Service Bulletin J41– 

24–043, Revision 2, dated August 21, 

2013. 

Conclusion 

We reviewed the relevant data, and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (79 FR 

52270, September 3, 2014) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (79 FR 52270, 

September 3, 2014). 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of this AD. 

Related Service Information Under 1 

CFR Part 51 

We reviewed BAE Systems 

(Operations) Limited Service Bulletin 

J41–24–043, Revision 3, dated June 16, 

2014. The service information describes 

procedures for an inspection of the earth 

post EP2 (left) and earth post EP4 (right) 

on the structure for the left and right 

power plants. This service information 

is reasonably available; see ADDRESSES

for ways to access this service 

information. 

Costs of Compliance 

We estimate that this AD affects 4 

airplanes of U.S. registry. 

We also estimate that it would take 

about 4 work-hours per product to 

comply with the basic requirements of 

this AD. The average labor rate is $85 

per work-hour. Based on these figures, 

we estimate the cost of this proposed 

AD on U.S. operators to be $1,360, or 

$340 per product. 

We have received no definitive data 

that would enable us to provide cost 

estimates for the on-condition actions 

specified in this AD. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. ‘‘Subtitle VII: 

Aviation Programs,’’ describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in ‘‘Subtitle VII, 

Part A, Subpart III, Section 44701: 

General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We determined that this AD will not 

have federalism implications under 

Executive Order 13132. This AD will 

not have a substantial direct effect on 

the States, on the relationship between 

the national government and the States, 

or on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify that this AD: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

2. Is not a ‘‘significant rule’’ under the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); 

3. Will not affect intrastate aviation in 

Alaska; and 

4. Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.
